Guaranteed | (888) 88-SOURCE | www.artisantg.com Preface Preface This manual describes how to use the Tektronix OTS Jitter and Synchronization modules. This manual is your primary source of information about how the modules function. The user interface also provides Windows Help files for further information on specific topics. How This Manual is Organized This manual is divided into four sections: Getting Started, Operating Basics, Reference, and Appendices. • Getting Started provides an overview of the modules and describes first-time operation. • Operating Basics explains the basic principles of operating the modules. The Operating Basics section also includes sample applications. • Reference provides a brief overview of the syntax and format used for remote commands and provides explanations and listings of the remote commands that may be used with the OTS system and the jitter and synchronization modules. • The Appendices provide a listing of specifications, default factory settings, list of acronyms, new information for the OTS91T3 and OTS91C3 cards, and other useful information. NOTE: To support 10Gb/s jitter generation, the OTS91T3 and OTS91C3 cards must be used in place of the OTS91T2, OTS91T1, and OTS91C1 cards. To support 10Gb/s jitter measurement, the 10Gb/s Transmit card must be either OTS91T3 or OTS91T2. The OTS91T1 Transmit card does not support jitter. OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com xi Preface Conventions This manual uses the following conventions: When referring to the modules and cards in a system, the definitions are: • A module is a technology solution incorporating a number of cards designed to work together to present the customer with a specific testing ability (the generic module cannot be ordered, the specific cards must be ordered). • A card is a subset of a module and refers to the individual, orderable cards that are plugged into the chassis. The names of front-panel connectors and LEDs appear in the manual in the same format as found on the front panel label, for example, OPTICAL IN and Tx EVENT OUT. When the user interface is discussed, all menus, name tags, and buttons appear in the manual in the same format as found in the user interface, for example, Enable COM2 and Output Pulse Trigger. In reference to terminology, the user interface may be set to either SDH or SONET references. The user manual provides SDH and SONET terminology separated by a slash (/). If no second terminology is present, the terminology is the same for both SDH and SONET. In reference to the instrument, the following conventions apply: • When referring to the mainframe or the whole system, the name OTS is used. • When referring to the two-card or three-card jitter module (Hybrid, Transmit, and Receive), the name OTS9200 is used. • When referring to each individual card, the card name is used, for example, Transmit. When referring to the synchronization module and because this module consists of only one card, the card name and module name are the same: OTS92S1. • NOTE: Some of the content found in this manual does not pertain to some instruments. Depending on the software revision and the options installed, some of the features described in these pages may not be available. xii OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Getting Started This chapter describes the preparation and initial setup of the OTS9200 and OTS92S1 modules. Also provided is a list of standard and optional accessories for each of the configurations: 10 Gb/s Jitter, 2.5Gb/s Jitter, and Synchronization. OTS9200 Product Description The OTS9200 Jitter module provides stable, repeatable jitter measurements capable of jitter generation and measurement. The module provides jitter output and jitter tolerance testing from 155MHz to 10GHz rates with exceptionally low intrinsic noise, wide jitter range with no range switching, no settling time, and high, stable jitter accuracy. The OTS9200 module utilizes a Tektronix-patented Digital Phase Analysis (DPA) technology employed on a high-speed SiGe chip. This revolutionary approach to jitter generation and measurements provides a number of significant testing advantages during testing. The DPA technology provides a much more robust signal containing none of the traditional problems of analog noise, gain error, distortion, and band limiting. Measurements can be made rapidly with no settling time delays. The OTS9200 adds another layer of testing capability to the OTS Product Family solution. The OTS9200 test module is comprised of three cards: Jitter Generation, Jitter Receiver, and Jitter Hybrid. The Jitter Hybrid card is required only for 10Gb/s testing. To test at the 155Mb/s to 2.5Gb/s rates, the OTS92T1 (Jitter Generator) and OTS92R1 (Jitter Receiver) cards are paired with the OTS9300 Multi-rate SONET/SDH module. To test at the 10Gb/s rate, the OTS92T1 (Jitter Generator), OTS92R1 (Jitter Receiver), and the OTS92H1 (Jitter Hybrid) cards are paired with the OTS9100 10Gb/s SONET/SDH module. Next Generation All-Digital Jitter Analysis This all-digital jitter solution provides consistent results, which in turn produce the following benefits: • Confidence in repeatability & consistency • Greater first-pass ratio • Results in higher yields • Eliminates the need for repeated tests • Saves time & money • Ensures compliance to standards NOTE: To support 10Gb/s jitter generation, the OTS91T3 and OTS91C3 cards must be used in place of the OTS91T2, OTS91T1, and OTS91C1 cards. To support 10Gb/s jitter measurement, the 10Gb/s Transmit card must be either OTS91T3 or OTS91T2. The OTS91T1 Transmit card does not support jitter. OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ...

Therefore, the test equipment can be removed from the testing equation thus increasing the value of the test results. No Settling Time, No Range Switching The all-digital nature of the jitter testing eliminates the need to use phase-locked loops for inferring jitter measurements, the traditional way of measuring jitter and suspect to a host of time-eating problems, such as slow settling and range switching requirements. The result of this lack of PLL circuits is a much cleaner signal output providing high resolution of the entire jitter range. The OTS9200 module eliminates both settling time and range switching, saving time and removing the guesswork range switching inevitably involves. Settling time is eliminated because the DPA technology time stamps each edge as it sees them. This ability decreases test times and enhances the thru-put of the testing system. Time-stamps Every Edge Jitter testing involves the measurement and generation of phase modulation. The test methodology has become increasingly digital as DACs, ADCs, DSPs, and time-stamp techniques have been incorporated. But the core of the methodology has remained an analog phase detector—one that converts phase (or time interval) to an analog voltage. As a result, the processing of phase has remained limited in frequency, amplitude, and accuracy. Some attempts to digitally time-stamp signal edges don't act in real time and miss data. The OTS9200 can measure phase by continuously time-stamping every edge and generate phase by placing each edge individually. 1-2 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ...

Before installing the module, verify that the OTS system is properly set up and powered OFF, as instructed in Steps 1 through 3 below: 1. Remove the unit from its shipping carton and place it on an anti-static surface. NOTE: Save all shipping cartons from OTS products. If returning the instrument is necessary, you will be required to ship them in their original shipping cartons. 2. Verify that the operating environment is within the limits detailed under the Environmental Requirement section in this manual. 3. Allow approximately 2 inches (5 cm) clearance for cooling. The OTS9000 requires this clearance for the front and rear of the unit. The OTS9010, OTS9030, and OTS9040 require cooling clearance on the left and right sides of the unit. 4. Install all required module cards into the chassis. If the module cards are not already installed, perform the following steps: CAUTION! When installing and removing modules from the chassis, power must not be present. Ensure that all power switches are in the OFF position and power cords are not installed before removing or installing modules. The OTS system does NOT support hotswap installations. Damage will occur if modules are swapped with power applied. A. Remove the module from its packaging, if necessary. CAUTION! All modules are static sensitive. When handling module cards, ensure that personnel are properly grounded and module cards are always placed on anti-static surfaces. If proper precautions are not taken, damage will occur. B. For those locations in which module cards are being installed, remove the blanking panels and air diverters. C. Carefully install each module card into a slot in the mainframe. Make sure that the module is lined up and fits cleanly with the connectors on the back plane of the mainframe. CAUTION! Beware of bending the pins of the connectors when installing and removing modules from the chassis. Backplane connectors with bent pins will cause damage to the both the module card and the chassis. To install the module cards, slowly slide the card into the desired slot. Make sure the card is lined up with the connectors and push down on the top release and up on the bottom release until the card snaps into place.

Verify that the power switch of the OTS chassis is in the OFF position. 6. Plug the unit into the appropriate AC Power source as follows: Table 1-4: Power Requirements AC Voltage 110 VAC 220 VAC Voltage Range 90 VAC - 132 VAC 180 VAC - 250 VAC Frequency Range 48 - 62 Hz 48 - 62 Hz CAUTION! If the OTS92T1 or OTS92R1 cards are installed with an unpopulated module slot to the right, you must install the Air Management Card. Installing the Air Management Card in the right-hand slot beside the card ensures the jitter cards are properly cooled and won’t be damaged due to overheating. Removing Module Cards To remove the module cards, perform the following steps: CAUTION! Before installing or removing module cards, secure dust caps onto optical connectors. If hanging loose when modules are moved, the dust caps can swing, damaging the EMI gaskets and potentially shorting to parts behind the front panels. All modules are static sensitive. When handling module cards, ensure that personnel are properly grounded and module cards are always placed on anti-static surfaces. If proper precautions are not taken, damage will occur. 1. Turn off the power to the OTS system. 2. Fully loosen the two screws found on the top and bottom of the module card. 3. Push up on the top release and down on the bottom release until the card is released from the connectors. 4. Carefully slide the module card out of the slot. NOTE: If a module card is removed, a blanking panel and air diverter must be installed to ensure proper airflow through the system. Failure to replace the air diverter and blanking panel could cause the system to overheat. 1-6 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Getting Started Slot Positioning of Modules OTS9200 Cards The slot into which each OTS9200 card is installed is very important to the proper operation of the instrument. Due to the tight integration between OTS software and OTS modules certain cards must be placed in specific locations to support many of the features, through-mode is an example of this. CAUTION! If the OTS92T1 or OTS92R1 cards are installed with an unpopulated module slot to the right, you must install the Air Management Card. Installing the Air Management Card in the right-hand slot beside the card ensures the jitter cards are properly cooled and won’t be damaged due to overheating. An OTS9200 module consists of OTS92H1, OTS92R1 and OTS92T1. Every OTS9200 module requires that the OTS92H1 Clock Recovery card be placed in the left-most slot of the module grouping followed by one OTS92R1 Receiver card and one OTS92T1 Transmitter card. A module may span the CPU in a multi-module system. Empty slots or slots containing non-OTS cards effectively end the grouping. NOTE: If the slot positioning rules are not followed, the module functions will be invalid. The transmitter and receiver functionality depends upon the absolute position and relative order of the module cards. OTS92S1 Card The OTS92S1 Synchronization card can only be placed into the highest numbered slot available in the chassis. In addition, only one OTS92S1 card is allowed per chassis.

Output jitter test - tests how much jitter is being generated by the device under test, and measures it. Tolerance – tests how much jitter can be tolerated by the device under test. Transfer – tests how much jitter is transferred through the device under test. OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com 1-21 Getting Started Jitter Test Applications This section briefly identifies typical applications for jitter testing. Jitter Output Testing Also referred to as jitter generation testing, jitter output testing measures the peak-to-peak jitter on the output signal of an instrument. The test is generally performed on a stand-alone network element and verifies that the output jitter of the instrument is within current standard specifications. Measurements are made using one or more defined bandwidths. The resulting value for each bandwidth is then compared against the specifications. The measurement period is normally 60 seconds and results are in UIpp or UIrms, depending on the specification. The basic setup, using an OTS system, for jitter output testing is shown in Figure 1-8. Figure 1-8: Typical OTS System Set-up for Jitter Output Testing Following the signal flow, the signal is outputted from the device under test (DUT) and fed into the Optical In of the OTS91L1 card. The signal is then converted into an electrical signal by the Optics card and sent to the electrical Data Out on the card. The signal can be split using a power splitter to allow BER and jitter testing simultaneously. Figure 1-7 demonstrates this option. One of the split signals goes to the OTS91R2 card for BER measurements. The other split signal goes to the OTS92H1 Jitter Hybrid card of the jitter module. From there the signal travels to the OTS92R1 Jitter Receive card for jitter measurement and analysis. 1-22 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ...

The only difference is that there is one less card; the Jitter Generation card is not used. This testing package provides a jitter test solution capable of performing jitter output testing but at reduced cost due to the absence of the Jitter Generation card. The basic setup for jitter output receive-only testing is shown in Figure 1-9.

Guaranteed | (888) 88-SOURCE | www.artisantg.com 1-23 Getting Started In-service Jitter Monitoring Another form of jitter output testing is called jitter interface generation testing or in-service jitter monitoring. This test uses the same method of testing as the standard jitter output testing. However, in jitter interface generation testing the device under test is already part of a network and not setup as stand-alone equipment. The basic setup, using an OTS system, for jitter output testing is shown in Figure 1-10.

Guaranteed | (888) 88-SOURCE | www.artisantg.com Getting Started Jitter Tolerance Testing Jitter tolerance tests a network element’s margins thus ensuring system compliance and reducing design costs. The principal of the test is very simple: at a specified jitter frequency and using sinusoidal modulation, what jitter amplitude is required to cause the element to violate an error performance criteria? In jitter tolerance testing, jitter is added to the signal input and BER measurements are taken from the signal output. The BER measurements taken at the output signal identify when the signal starts to degrade. The point just before that degradation is the jitter tolerance of the output signal, or of the device under test. Customarily, a number of different jitter frequencies are tested to determine the complete characteristic of the device under test, which is then compared to the standards. Figure 1-11 demonstrates a typical OTS system set-up for jitter tolerance testing. Figure 1-11: Typical OTS System Set-up for Jitter Tolerance Testing NOTE: When using the OTS equipment for this test, make sure that on the 10Gb/s Transmitter card the Timing Source chosen is “Jitter”. Otherwise the jitter signal will not be transmitted. OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com 1-25 Getting Started Jitter Transfer Testing Jitter Transfer testing uses the same set-up as jitter tolerance, as shown in Figure 1-11. Jitter transfer measures the jitter carried on the output signal. A Narrow Band sinusoidal jitter signal is introduced to the device under test. The measured output signal is then compared to the input jitter signal. The ratio of this comparison identifies the jitter transfer of the device under test. Figure 1-12 demonstrates a typical OTS system set-up for jitter transfer testing. Figure 1-12: Typical OTS System Set-up for Jitter Transfer Testing Jitter Transfer testing requires that a calibration run be performed on the device under test before the actual test is run. To perform a calibration run, the device under test is looped back into itself and then the output signal measured. This sinusoidal signal is then compared to the actual test results and removed from the final results. 1-26 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ...

The following jitter tolerance tests are available: ο Tolerance (Power Penalty) – Acceptance ο Tolerance (Power Penalty) – Measure ο Tolerance (Onset) – Acceptance ο Tolerance (Onset) - Measure A jitter tolerance test verifies a network element’s ability to perform its function in the presence of jitter on its input signal. This is traditionally measured in one of two ways: The onset-of-errors method starts with a signal that is error-free when no jitter is applied. Jitter of a specified frequency and amplitude is then applied to the input of the device under test and its output is monitored for errors for a specified time interval. If, during this interval, the number of errored seconds – one-second intervals in which one or more errors occur – is at or below a threshold, the device under test can tolerate the jitter applied. The 1-dB optical power penalty method uses an attenuated input signal adjusted to achieve a specified error rate, typically approximately 100 errors per second with no jitter applied. The input power level is increased by 1 dB; this action reduces the error rate. Jitter of a specified frequency and amplitude is then applied and the error rate again measured. If the error rate with jitter is at or below the error rate initially measured at reduced power, the device under test can tolerate the jitter applied. The fully automated compliance test applies jitter and measures errors at a series of frequency/amplitude points. The OTS9200 performs both jitter tolerance acceptance tests and jitter tolerance measurements, as follows: ο Acceptance test: functions as described above, it applies jitter at a set of particular frequencies and amplitudes, and verifies that the device under test functions under those conditions. Any point for which the device under test cannot tolerate the specified jitter causes the test to fail. ο Measurement test: attempts to determine the maximum level of jitter with which a device will function. The OTS9200 applies jitter at the same frequencies as for the acceptance test, but at each frequency, it varies the jitter amplitude to find the level at which the device under test fails the selected criterion. The highest level at which the device under test passes becomes the measured jitter tolerance for that frequency. Tolerance Test Condition The Tolerance Test Condition dropdown list offers a choice of the four bit error conditions that may be monitored for jitter tolerance testing. Bit error conditions available are B1, B2, B3, and Payload Bit. Mask Selection The Mask dropdown list offers a choice of jitter tolerance masks applicable to the currently selected line rate. Both standard (fixed) masks and user-defined masks appear in this list. 2-32 OTS9200 User Manual Artisan Technology Group - Quality Instrumentation ...

The age of a file is determined based on the ‘Delete files by oldest’ setting. The number of files present counts ‘sets’ of results data (a summary file and its associated history file count as one ‘results file set’). When enough files have been added to the list to meet all enabled limits the indicated files are either deleted or moved to the indicated directory. If processing of a given file fails (possibly due to file permissions or the destination directory being unavailable) processing of files will proceed through the remainder of the list. For a move to complete successfully, the target directory must exist and be accessible to the OTS system. If a move fails, the system will simply retry the operation next time the cleanup process runs. The final control in the dialog allows the user to control how frequently the cleanup process runs. It is guaranteed that cleanup passes will occur no more frequently than specified here. It is possible for the system to defer cleanup for a longer interval as necessary.

It provides the following functionality: Access to test results files, either on the OTS system or on the file system of the computer that is running ResultsViewer Display of results data – Cumulative Results, Analysis, and History – with the same presentation as the OTS User Interface, TekUI Printing of Cumulative Results and Analysis data, and export of the same text to an ASCII text file or the Windows clipboard Export of Cumulative Results, Analysis, and History data in delimited ASCII-text form, to a file or to the Windows clipboard Printing of History data to a graphical form Copying results files to a directory on the local file system NOTE: The results of a test are stored in two files, with the same file name but different extensions. One has extension .sum (summary information) and one has the extension .his (history data). Although ResultsViewer file selection operations involve only the .sum file, both files are used and must be present and in the same directory. Therefore, If you copy a test's results files to another computer or directory, you must copy both the ".sum" and the ".his" files If you rename a test's results files, you must rename both the ".sum" and ".his" file to have the same name If you use the File menu Save As function to copy the currently active test results to a directory on the local computer, the operation creates both the “.sum” and the “.his” files under the specified name 2-52 OTS9200 User Manual Artisan Technology Group - Quality Instrumentation ...

IEEE 488.2 Common Commands Description ANSI/IEEE Standard 488.2 defines the codes, formats, protocols, and usage of common commands and queries used on the GPIB interface between the controller and the instruments. The OTS system complies with this standard. Command and Query Structure The syntax of an IEEE 488.2 common command is an asterisk (*) followed by a command and, optionally, a space and parameter value. The syntax for an IEEE 488.2 common query is an asterisk (*) followed by a query and a question mark. The following are examples of common commands: *ESE 16 *CLS The following are examples of common queries: *ESR? *IDN?

Guaranteed | (888) 88-SOURCE | www.artisantg.com 3-7 Reference: Remote Commands ~ Syntax Block Format IEEE-488 block format is a means of encoding arbitrary binary data, including characters that aren’t valid in text strings, for transmission over a GPIB link. The format is most easily explained with an example. This is a block containing 16 bytes of data: #216abcdeFGHIJklmnop where: ‘#’ denotes the start of a block ‘2’ is the number of digits that follow, to represent the byte count in the block ‘16’ is the number (represented by two decimal digits) of data bytes ‘abcdeFGHIJklmnop’ is the 16 data bytes in this example The OTS system uses blocks in commands and queries for overhead data and section trace sequences; the descriptions of these commands include the number of bytes expected or sent. Hex Block Format The GPIB can transmit eight-bit binary data without problems. But the OTS system can also be controlled over RS-232 serial links and Telnet protocol over network links. These may not be able to send eight-bit data or ASCII control characters. For this reason, the OTS remote command system implements an alternative block format called hex block format in which each byte of binary data is sent as two hex digits using the characters 0 to 9 and A to F. Blocks in hex format thus consist of twice many characters as the corresponding blocks in binary format. The block in the example above would be, in hex format, #2326162636465464748494A6B6C6D6E6F70 where ‘#232’ is the prefix for a 32-character block ‘61’ is the hexadecimal representation of “a,” the first character in the block ‘62’ is the hexadecimal representation of “b,” and so on. Note that the block’s count of data bytes is doubled, representing twice as much data as in the binaryformat block. The OTS system must be explicitly set to transmit or receive blocks in binary or hex block format. See the description of the command. 3-8 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Reference: Remote Commands ~ Syntax SCPI Commands and Queries SCPI is a standard that provides guidelines for remote programming of instruments. These guidelines provide a consistent programming environment for instrument control and data usage. This environment uses defined programming messages, instrument responses, and data format across all SCPI instruments, regardless of manufacturer. The OTS system uses a command language derived from this SCPI standard. The SCPI language is based on a hierarchical tree structure, as shown in Figure 3-1, that represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes. SENSe Root node Lower-level nodes MEASure SECTion LINE PATH WINDow OVERhead APSTime POINter Figure 3-1: Example of SCPI subsystem hierarchy tree You can create commands and queries from these subsystem hierarchy trees. Command Format A command sets the value of an instrument parameter or initiates an instrument event. A command consists of one or more alphanumeric keywords separated by colons; this part is called the header. If the command includes parameter values, these appear after the header and separated from the header by a space. Multiple parameter values are separated by commas. Example The command to set the OTS-9100 Receiver input threshold voltage to 100 mV is :SENSE:INPUT:THRESHOLD 100 where :SENSE:INPUT:THRESHOLD is the header, and 100 is the parameter value. Query format A query fetches the current value of an instrument parameter, measurement, or status condition. A query consists of a header, like that of a command, followed by a question mark. If a query includes parameter values, these appear after the question mark and a separating space. Example The query to fetch from the OTS-9100 Receiver the current setting of the input threshold voltage is :SENSE:INPUT:THRESHOLD? The response to this query might be the value, 100 - it might also be formatted as a complete command, for example: :SENSE:INPUT:THRESHOLD 100 as controlled by the :SYSTEM:HEADERS and :SYSTEM:VERBOSE commands (q.v.).

Guaranteed | (888) 88-SOURCE | www.artisantg.com 3-9 Reference: Remote Commands ~ Syntax Parameter types and formats Parameter values may be of several different types, e.g., integer numbers, floating-point numbers, selections from a list of particular values, strings, etc. The following are the parameter types that appear in OTS system remote control commands. <NR1> An integer number. <NR2> A decimal number with integer and/or fractional parts, e.g., 12.43 <NR3> A decimal number in scientific notation, e.g., 1.243E1 NOTE: A command parameter value specified as <NR2> or <NR3> may be entered in either standard or scientific-notation formats. A query will return its value in the format indicated. <Enum> A selection from an enumerated list of values that appear as alphanumeric keywords, usually with a mnemonic value. For example, the command that specifies the payload inserted into the generated signal appears as: :SOURCE:DATA:PAYLOAD:PATTERN <Enum> followed by a list of possible values, PRBS23A Standard PRBS 223-1 pattern PRBS23I Inverted PRBS 223-1 pattern ZEROS Constant zero data ONES Constant one data The command must include one of these values; the corresponding query returns one of these values corresponding to the instrument’s current setting. <Boolean> A binary value that typically indicates whether a function is on or off, enabled, or disabled. Querying a Boolean parameter always returns 0 or 1, never OFF or ON. Boolean values may be specified as follows: <String> 3-10 0 or OFF off, disabled 1 or ON on, enabled A string of characters, delimited by either apostrophes ‘ or quote marks “. Strings must, in general, be composed of ASCII printing characters and may not contain the apostrophe or quote mark used as the delimiter. OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com Reference: Remote Commands ~ Syntax <Block> An array of arbitrary binary data (bytes), including characters not in the ASCII printing character set. A block is transmitted as a block header followed by data bytes, as in the following example: #216ABCDEFGHIJKLMNOP in which: ⇒ The # character indicates that what follows is a block of data ⇒ The first digit, 2 in this example, is the number of digits in the block length field ⇒ The next digits, of which there are two in this example, indicate the number of bytes of data that follow. In this example, there are 16 bytes, so the block length field is 16. There are two digits in "16," so the character "2" following the "#" is the digit count. ⇒ The bytes that follow, ABCDEFGHIJKLMNOP, are the actual data. The number of bytes of data must match the number indicated by the block header. Optional and alternative parameters Some parameters are optional; these appear in brackets ([ ]): :SENSE:STATUS:LEDS [<NR1>] The command description includes the meaning of the parameter and the effect of leaving it out. Some parameters may accept data of more than one type; the alternatives are shown separated by a vertical bar. For example, :SYSTEM:COMMUNICATE:GPIB:PRIMARY <Enum>|<NR1> means that the command can accept either a keyword from the given enum list or an integer numeric value.

This manual shows these short forms as a combination of upper and lower case letters. The upper case letters tell you what the accepted short form should consist of, as shown in Figure 3-2, you can create a short form by using only the upper case letters. The accepted short form and long form are equivalent and request the same action of the instrument. Long form of a command SYSTem:COMMunicate:SERIal:COM1A:PROMpt Minimum information needed for accepted short form Accepted short form of a command and parameter SYST:COMM:SERI:COM1A:PROM Figure 3-2: Example of abbreviating a command NOTE: The numeric part of a command or query must always be included in the accepted short form. In Figure 3-2, the “1” of “COM1A” is always included in the command or query. Controlling Responses to Queries You can control the form of responses returned by queries by changing the parameter values of SYSTem:HEADers and SYSTem:VERBose. These two commands control whether the query nodes are returned with the response, and, if the query nodes are returned, whether they are in the long or short form. SYSTem:HEADers controls the presence of the query nodes, and SYSTem:VERBose controls the length of these nodes.

SOURCE:DATA:STRUCTURE is the same as source:data:structure and SOURCE:data:Structure No embedded spaces are allowed between or within nodes. correct: SOURce:DATA:STRUcture incorrect: SOURce: DATA: STRUcture incorrect: SO URce:DATA: STRU cture Slot Specifiers The OTS system can contain multiple modules of the same type, e.g., more than one receiver, more than one transmitter. Any module-specific command or query may include, as a numeric suffix on the header’s first keyword, the slot number of the target module to indicate the particular instance of that module for which the command or query is intended. For example, the command :SOURCE5:INSERT:ANOMALY:MODE CONTINUOUS is intended for the transmitter module in slot 5. Slot specifiers are indicated by <Slot> in the command listings. Slot specifiers are optional; if a slot specifier is omitted, the command or query is directed to the lowest-numbered slot that contains a module for which the command or query is valid. 3-14 OTS9200 and OTS92S1 User Manual Artisan Technology Group - Quality Instrumentation ...
